two to many

My wife saw these at H.D. and really like them, I was a little taken back by the price. So I built my own only problem I built 2 to many I’m thinking of joining them together somehow and make a trellis for a pathway

These two and the six others were built from 2×6 fir bought at the home center. I sealed them really good and six of them have been out doors for almost two years. The stain is fading a little but the trellises themselves are still in good shape
